Are these fans 3 pin or 4 pin?

Three pin fans, but they will work with four pin connections. I use mine with and four pin MSI motherboard.

I can't say for sure, I used the molex plug. I don't see any reason why it wouldn't work with the 3 pin connector. Some motherboards even control the fan speed when connected with the 3 pin connector.

Yes, comes with a 3 pin connector and a screw set for the fans, they run really well

Black is 0 V (ground or negative), the next to it, yellow, is the + 12 V (positive). Next green = sensor of rotation speed, then blue is the additional, programmable 0-12 V (PWM). 2nd and 4th are sometimes interchangable, but not always. Just sticking a second wire from the system board to the 4th fan's won't activate some of the fans. But putting a PWM into the second wire of a fan is more likely to control it. At fans it's better to look at the position in the connector, rather than colors. 0 V is always the first, edgemost, corresponding to the plastic tooth. The 3rd (sensor) is at the opposite tooth, and the 4th PWM is the pin protruding beyond the plastic tooths to the side. Looking like an additional contact "added later" to the fan standard. And in all computer wire sets, i guess, a black wire is the 0 V, and if there's no black, then a white should exist, and the white is 0 V.

The PSU itself has standard connectors. You can purchase adaptors to change the 3 or 4 pin case fans into the type this provides. Most fan connectors are provided by the motherboard, in a normal setup.

No. It is designed for a computer motherboard with 3 or 4 pin. It is internal fan for custom build.

4 pin works fine in an 8 pin slot, just leave half of it free it will run just fine.

3 pin. It will connect to a 3 pin header but it will run at full speed in this configuration. Full speed is still a very slow and quiet 900rpm.

No far as I know it just works with 3 you would have to buy some 3to4pin adapters but it works very well with 3pin fan

It is a 4 pin. It will work on a 3 pin connector, but it will be a single speed (the 4th pin is the PWM/speed control pin). Make sure you're aware that its max TDP cooling capacity is 65 watts). I was using this cooler on a 65w court, and it would not keep it cool enough for me in an ITX build....I changed it out for a stock cooler....a bit more noise, but the cpu now stays in the upper 30c, where as with this cooler temps were always in the high 50s.

There are two 4 pin (PWM) fan headers - one for the cpu fan (CPU_FAN) and one chassis fan (SYS_FAN1). There are also two 3 pin fan connectors for NON pwm fans (SYS_FAN2 and PWR_FAN).

It comes with 2 fans w/ no LEDs one on the top (140mm) and one on the back (12mm). Both are 3 pin connectors.

Funny thing is.. They connect to the motherboard.. You will see were they connect and say fan1 to fan2.. Awkward set hp of how it works..

I'm not aware of a four pin on a motherboard. Like it says, connect it to the power supply. It works fine as a 5volt or 12volt for a full speed fan.

All the fans are 3 pin, and come with molex pass through (male/female) adapters which allow for daisy chaining to a single PSU hookup. This applies to all HAF Stacker products currently. I own the 935 and two 915F modules in a single stack.

I purchased the 140 mm, though I would assume they should be the same. the fans themselves are 3 pin if you are going to attach them directly to your motherboard but they also come with 3 pin to molex adapters (which I used) in order to connect them directly to the power supply. I was able to attach two fans in series to one of my power supplies molex strips.

Both of the fans join together to make a normal 4 pin fan connector. Even with a very basic motherboard, I doubt you'd have any trouble.
